This is a performance parts kit for building a Predator 212cc non-Hemi engine for mini bike and go-kart racing. It combines a high-lift camshaft, a billet connecting rod, a flat-top piston, a lightweight flywheel and heavier valve springs.
The camshaft has a .308" high-lift profile with performance valve timing. The 3.308" billet aluminum connecting rod is paired with a 70mm flat-top piston, which raises the compression ratio. The flywheel is built for 10,000 RPM operation and has a lightweight construction that reduces rotational inertia.
The two 26 lb valve springs are meant to prevent valve float at high engine speeds, so the valves follow the cam profile. The kit also includes two oil drain plugs, a spark plug and a gasket set.
